Description

A COBOL-85 compiler for 16 bit OS/2 and DOS introduced in 1988 as version 4 and with some limited Windows 3 support in version 4.5 introduced in 1990. In addition to adhering to the COBOL-85 standard the compiler comes with some support for IBM's DB/2 in version 4 and ANSI 85 definition, X/Open XPG3 COBOL definition, COMP-1 32 and 64 bit floating point extensions as in IBM OSVS COBOL and IBM VS COBOL II in version 4.5.

The actual compiler was licensed from Microfocus, the rest of the tools like the debugger and editor were in-house developments from Microsoft.
